When images are used in a responsive container on web design, because the container can change to any width:height ratio, a group shot could end up cutting off people’s faces. A nice photograph following “rule of third” could end up with no object in view. Responsive images face the challenge of how to keep the focused objects/area in view, this jquery plugin is here to solve the problem.

Responsify.js does the following:

It allows you define a focus area on an image using data-focus-xxx tag

It takes in the focus area data from the image, calcuate the image’s container’s size, resize and position the image accordingly, make sure the focus area is always in view and in the best position possible

If you are looking for a lightweight jQuery plugin for complex two-way data binding in real time, jQuery.my might be the perfect solution.

Here’s how it works: The tool mutates the object given as a data source, reflecting interactions between the user and the interface. Data bindings, facade appearance and CSS styling of an app are all defined using single manifest, which is standard javascript object. Manifests are JSONable.

jQuery.my provides comprehensive validation, conditional formatting, complex dependencies, runtime form structure manipulation. $.my forms can run nested, each jQuery.my instance can be a composite control for parent form.

Syntax of $.my manifest is very simple, lean and unobtrusive. There exist specialized in-browser IDE for $.my apps authoring. This IDE is a built-in component of cloudwall.me system.

The result is a fully interactive set of tools, tables, curves and layouts that can work in a variety of applications. Check out the demo to see how it can work for you.

This allows the image on the right to show through the container.The widget uses jQuery custom movement events to support this slider movement.

Color

Stroke width

Circle width

Shawdows

Triangle color, size and position

Handle radius
